Area Forecast Discussion National Weather Service San Diego CA 951 AM PDT Mon Mar 30 2020

SYNOPSIS. Tranquil weather will be on tap for the majority of the work week. Dry and mild weather through Tuesday with a push of stronger onshore flow for Wednesday and Thursday. This will bring a slight cooling trend mid week with a return of night and morning low clouds and patchy fog for coastal and valleys areas. Friday will be warmer followed by a cooling trend for next weekend with more night and morning low clouds for the coast and valleys.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

SHORT TERM. (Today through Thursday) .

A weak area of high pressure will make a brief visit to Southern California today and tomorrow as pressure heights continue to rise across the Desert Southwest. This will bring mild temperatures today, peaking tomorrow for most, with temperatures attempting to reach the 80 degree mark for parts of the Inland Empire. This will all be determined by cloud cover tomorrow, as some models depict a cloudier scenario than others.

Mother Nature quickly whisks away our warm and friendly area of high pressure to the south as a coastal low invades the Pacific Northwest. This will bring a troughing pattern across the state and some tightening of the surface pressure gradients from the Sierra to our local mountains. Temperatures will slide down back to below normal values with some gustier onshore breezes in the mountains and deserts, where winds could clock speeds of 30-40 mph. Coastal low clouds will be making their return with this system as well, as a weak coastal eddy develops offshore. We may see areas of fog along the coast, though confidence is still low at this time.

LONG TERM. (Friday through Sunday) .

The weather pattern looks to remain in a somewhat active pattern as we get into the weekend. Long range ensembles predicting a brief rise in heights Friday, leading to some warmer and comfortable weather. The atmosphere is expected to once again enter a pattern of cooler weather as some models produce a smaller initial impulse of lowering heights across California on Saturday with a larger system possibly coming down from the Gulf of Alaska on Sunday. Ensemble guidance is in fairly good agreement with this pattern taking hold through much of the weekend and even into early next week.

AVIATION. 301530Z . Coast/Valleys . Expect CLR-SCT conditions through this evening. SCT low clouds will form over the coastal terminals KSAN/KCRQ/KSNA beginning after 02Z. Periods of BKN MVFR/IFR conditions with ceilings 800-1200 ft MSL are expected 09-14Z Tuesday. Expect westerly winds around 10 knots in the afternoons.

Mountains/Deserts . Clear with unrestricted vis today and tonight.

MARINE. No hazardous marine weather is expected through Friday.

SKYWARN. Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.

SGX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.

PUBLIC . APR AVIATION/MARINE . Moreland

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
